Abstract
Movable sensing arrangements are prone to damage, unable to position a load engaging device relative to a load for stacking purposes, and unable to controllably position the sensing arrangement. A movable sensing apparatus having a housing and first and second signaling devices mounted in the housing is provided. A guide rail assembly elevationally movably mounts the housing on a carriage assembly and an actuator controllably elevationally moves the housing along the guide rail assembly. A coupling connects the actuator to the housing and releases the housing from connection with the actuator in response to a force of a preselected magnitude being applied to the housing. Thus, the problems related to damage, stacking, and positioning are reduced. The movable sensing apparatus is particularly suited for use on an automatic guided unmanned vehicle having a lift mast assembly.
